The proposed effort covers the engineering aspects of a magnetic field source to be used in a table-top demonstrator of magnetic refrigeration. A prototype magnetic field source, based on the Halbach or "magic-ring" concept, will be designed, constructed and tested in the Phase I effort. The proposed device is based on an innovative concept that is simpler than current magic-ring configurations. ...

As System-of-Systems (SoS) become more complex, interactions and latent emergent behaviors become difficult to identify and control. Unmanned Autonomous Systems (UAS) are a prime example of SoS that are both critical and difficult to assure. Drawing upon prior work into multi-criteria decision making (MCDM), DeVivo AST has developed TOP Score, a software tool that facilitates the modeling and anal ...

The overall objective of the proposed project is to develop new injury criteria, model based risk assessment methodology, and a software tool to assess neck injury risk from head supported mass (HSM) loading. Based on the foundation of Phase I feasibility studies, the proposed Phase II work will focus on model enhancement, extension and validation, risk assessment, and software integration and tes ...

Current methods to discern the differentiation state of stem cells are time-consuming, labor-intensive, costly, invasive, and consequently, ill-suited for clinical applications. To overcome these limitations, we propose to develop a microfluidic stem cell analyzer for accurate, non-invasive identification of the cell differentiation state in conjunction with automated cell sorting at high-throughp ...

Current methods for stem cell isolation are time-consuming, costly, and labor-intensive, and ill-suited for point of care applications. To overcome these limitations, we propose to develop and demonstrate a high-throughput, non-invasive, microfluidic stem cell analyzer to enable a rapid isolation of high-quality stem cell products from clinically relevant samples. Our technology enables significan ...

Many geospatial technologies and modeling techniques exist, especially for 3-D visualization of correlated layers of data. A gap remains in integrating the unstructured world of voice, chat, and free-form text communications to the more structured world

The proposed electrostatic atomization process has been successfully applied within the diesel injection and paint spray industries to generate a priori specifiable droplet-size distributions with near uniform droplet dispersivity. Energetically efficient droplet development with electronically controlled uniform mean droplet sizes between 10 and 100 um range have been demonstrated, with range ex ...

Spectroscopic ellipsometry is recognized as the gold standard in noncontact characterization of the refractive index and thickness of a thin optical film or film stack on a substrate. However, it suffers from a number of shortcomings, perhaps the most important of which is the time required to perform a single measurement. Moreover, manufacturers are interested in comprehensive evaluation of thin ...

Propagation Research Associates, Inc., (PRA) proposes to redesign our existing Enhanced Tropospheric Effects Compensation ground-based radio occultation (RO) measurement system, which was developed, prototyped, and demonstrated under previous SBIR contracts, for the purpose of optimizing cost and performance. Assimilation of space-based RO measurements into numerical weather models is a proven met ...
